There is already a question about the number of research mathematicians here, but I was wondering :

is it possible to estimate the number of graduate students in mathematics worldwide in 2019 ? (Note that, especially since not all of GS stay in academia, it is quite different from the other question.)

Ideally, what I'm looking for is a graph since 1950, with a break-up by country.

$\begingroup$I think I found some data for France : this link fr.statista.com/statistiques/618628/… says that in 2017 there were 2,406 doctoral students in mathematics & their interactions. I'm especially curious about China and India though.$\endgroup$

$\begingroup$this seems accurate for a developed country (for France, with a population of 67 million, your estimate would be some 5000 graduate math students, within a factor of two of the correct answer), but I would think it vastly overestimates undeveloped parts of the world.$\endgroup$

$\begingroup$Care to give us some error bars on these estimates, Proxava?$\endgroup$
